Your code is not running in a browser, it is only running inside an HTML5 runtime engine (see this blog for details). Things like printing, URL bars, tabs, etc. are features of the browser that connect the HTML5 runtime engine to host OS services. The environment your app is running in is not a browser, so you have to connect to those host OS services through Cordova plugins. This means that you need to search for a "cordova print plugin" to find something that might do what you want. If you do not find one you will have to write one.
The Intel XDK creates standard Cordova apps (aka PhoneGap apps).
